commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

up N

I did not like two things in the submitted commands and fixed it here:

1) If I do cd - afterwards, I want to go back to the directory I've been before

2) If I call up without argument, I expect to go up one level

It is sad, that I need eval (at least in bash), but I think it's safe here.

eval is required, because in bash brace expansion happens before variable substitution, see http://rosettacode.org/wiki/Repeat_a_string#Using_printf

function up { i=$1; while [ $((i--)) -gt 0 ]; do cd ../ && pwd; done }
function up { for i in `seq 1 $1`; do cd ../ && pwd; done }

You can also remove the "&& pwd" if you don't want it to print out each directory as it moves up.

diff <(cd dir1 && find . | sort) <(cd dir2 && find . | sort)
cd ~/.msf4/loot && cat *mscache* | cut -d '"' -f 2,4 | sed s/\"/\:/g | tr -cd '\11\12\40-\176' | grep -v Username | cut -d : -f 1,2 | awk -F':' '{print $2,$1}' | sed 's/ /:/g' > final.dcc.hash

Assumes you've cd'd to the folder in which all your git repos reside; you could run it from ~ without -maxdepth, although that might make find take quite a while longer.

If you have several processor cores, but not that much ram, you might want to run

git config --global pack.threads 1

first, since gc-ing can eat lots of ram.

cd () { command cd $1 && ls ; }
function cdf () { [ -f $1 ] && { cd $(dirname $1); } || { cd $1 ; }; pwd; };

Had trouble with the other function, because of missing semicolons. (According to my bash on OS X)

alias md='mkdir -p'; alias rd='rmdir'; mcd () { mkdir "$@" && cd "$_"; }

Functions: alias cd mcd mkdir

I realise that this is just a reiteration of another entry (regardless of whether I came up with all this all by myself), but I would like present my additional alias' in context as a method of managing your directories. Rather convenient.

function _xterm_cwds() { for pid in $(pidof -- -zsh) $(pidof zsh); do reply+=$(readlink /proc/$pid/cwd) done }; function xcd() { cd $1 }; compctl -K _xterm_cwds xcd

User: aartur
Functions: cd pidof readlink

It gives a 'xcd' command for changing directory to one of CWDs of other ZSH processes (typically running in a terminal emulator). Useful for single-windowed terminal emulators like XTerm or Rxvt which don't have ability to pass CWD of one shell to another.

If you have long and complicated folder names this might ease your work.

add this into .bashrc

Creates a directory and then cds into it directly

up() { [ $(( $1 + 0 )) -gt 0 ] && cd $(eval "printf '../'%.0s {1..$1}"); }

`up 3` will climb the directory tree by three steps. `up asdf` will do nothing, and returns exit code 1 as an error should.

set str=user_pref("browser.startup.homepage", "http://www.fcisolutions.com/"); cd = "%APPDATA%\Mozilla\Firefox\Profiles\*.default\" echo %str%>>prefs.js

Pros: Works in all Windows computers, most updated and compatible command.

Cons: 3 liner

Replace fcisolutions.com with your site name.

cd /System/Library/LaunchDaemons; sudo launchctl load -w com.apple.metadata.mds.plist
up() { local x='';for i in $(seq ${1:-1});do x="$x../"; done;cd $x; }

I wrote this a long time ago, wondering why this wasn't floating around somewhere out there (at least not where I could find).. this seems much more simple than multiple aliases and can cd out of directories easier.

cd "~/Music/iTunes/iTunes Media/Mobile Applications";ls > filepath
up () { if [ "${1/[^0-9]/}" == "$1" ]; then p=./; for i in $(seq 1 $1); do p=${p}../; done; cd $p; else echo 'usage: up N'; fi }

This is like `cd -` but doesn't echo the new directory name, which is preferable (to me) for an alias, e.g.

alias cdo="cd $OLDPWD"

Somehow, i prefer forcing to rm interactively to accidently rm'ing everything...

Functions: cd diff find

Output of this command is the difference of recursive file lists in two directories (very quick!).

To view differences in content of files too, use the command submitted by mariusbutuc (very slow!):

diff -rq path_to_dir1 path_to_dir2
cd /path/to/dir && command_or_script; cd -;
